 influence these birds in their choice of a summer home. 



It was formerly believed that the Bam Swallows, and others, 

 passed the winter torpid in mud at the bottom of lakes, and 

 in caves. Much astounding evidence has been produced to 

 prove the coiTectness of this absurd theory, which is, however, 

 too unnatural to exist long under the rule of modern science. 

 Wilson is eloquent in his condemnation of this belief, and 

 considers it too ridiculous to be worthy of serious refutation, 

 which is, in fact, the case. 



d. The young Barn Swallows often utter a series of twit- 

 ters, which resemble the laugh of a tickled child, and the older 

 birds also have various twitters, some of which are sprightly 

 and musical. 



e. I shall not describe at length the twitters and guttural 

 cries of the various Swallows, both because they are more 

 easily learned than described, and because, when described, 

 they can hardly aid one in distinguishing the different species. 



The Bam Swallows are so well known that I have men- 

 tioned no details in their habits. Their colonizations, their 

 constantly uttered notes, and their flights, ^.re familiar to nearly 

 all, and the latter have long since been made the theme of
